About this item

Maximize your body’s protective capabilities with one of the most powerful antioxidants known to modern nutritional science. The phenolic compounds found in olive leaves have long been known to exhibit impressive antioxidant activity by scavenging reactive oxygen species known as free radicals. Now, research indicates that one of these compounds may stand above all others in free radical-scavenging capability: hydroxytyrosol. A metabolite of the phenolic compound known as oleuropein, hydroxytyrosol packs an antioxidant punch few other substances can match, protecting against all five common free radical species with roughly 10 times the oxygen radical absorbance capacity (ORAC) of green tea. That’s a level of broad-spectrum antioxidant protection that surpasses blueberries, strawberries and even acai berries with a wide range of potential benefits for the brain, cardiovascular system, immune system and more.Swanson Maximum Strength Olive Leaf Extract veggie caps feature Olea25®, an ultra-potent, state-of-the-art extract made exclusively from 100% organically grown olive leaves. The most powerful olive leaf extract on the market today, Olea25® is standardized to an impressive 25% hydroxytyrosol content—the same concentration used in clinical studies. It’s a great way to beef up your body’s antioxidant arsenal for optimal mental and physical vitality.
